Light Control

LED Light Control Unit

New exterior lighting functions such as adaptive front lighting systems and LED-based lighting applications (e.g. Low/High Beam) are leading to more complex control strategies for headlamps. We support carmakers as well as headlamp system suppliers with new electronic control units to fulfill the specific needs of these new lighting functions.

Benefits & Features

  • Automatic adaption to newest LED illuminants
  • Control of LED front lighting to support energy efficiency and CO2 reduction
  • Scalable product platform to apply adaptive and LED lighting functions for all vehicle segments
  • Supporting design freedom by OEM specific light functions
  • Available for both OEMs and headlamp system suppliers

Technical Information

  • Usage of ASSP LED driver family for high output flexibility
  • High dynamic range LED dimming (PWM, current)
  • Scalable mechanic and hardware concepts (e.g. IP69)
  • Supporting state-of-the-art EE architecture (e.g. Autosar, CAN)
  • Software modules for thermal management and stepper control

Pixel LED Light System

We provide an ECU platform solution to manage stepping from mechanically actuated glare-free, high-beam systems towards fully flexible control of up to 100 pixel. The system architecture allows a scalable solution with a flexible number of satellite boards for easy extension of  headlamp functionalities without an impact on the main ECU.

Benefits & Features

  • Less moving mechanical parts inside headlamp
  • Design freedom
  • Advanced lightfunctions: glare-free high-beam, bending light
  • Various welcoming and goodbye light scenarios possible
  • Scalable system architecture up to 100 pixel
  • Covering high dynamic range requirements of LED and pixel light applications

Technical Information

  • Distributed system with control unit and satellite boards
  • Usage of ASSP LED driver family for high output flexibility
  • New, scalable cooling and housing concept for the ECU
